Update May 17 2015. As far as I corcen with my old airfow scheme, too much positive pressure and the PSU has to works to hard, this is my third update and also the last one for this case, and I am totally happy now. As you can see in this photos, my case now is FLOATING!!!! I changed the original feet with my custom feet I made the other day, leads to better breathing under the case.
After quite some consider ration, I decided to change my radiator as an intake, and now add an 92mm slim fan on the bottom for total of 2 fans as intake (radiator fan on the back and the top 140mm Prolimatech slim fan) and 2 as exhaust (PSU and 92mm noctua slim fan - recommended, since it provides clearance to take the mobo on and off, normal 25mm fan will get in the way. Of course, as before, Dremel and patience were my best friends. I taped my new fan on the bottom, just as my top fan - as now has a proper removable dust filter on it (I did have the same one but on the bottom of the fan and dust collected on the blade so I decided to change that).
I also add a self-trim grill for the Noctua fan since I don't know what might struck under the case somehow. Oh, and proper dust filter for the rear Corgar Vortex radiator fan
So, what about the temp? I test it another day, as the graph you can read. it seems a bit worse, but I tested it on a day that at least 5C (11F) higher ambient temp than the other day. It's the revision 3 in light green color
I'm pretty much happy now, so if anyone needs any help with modding the case or anything, let me know, I'll be happy to help
